Home / Example of power supply relay protection
Protective relays work in conjunction with various electrical protection and control devices, such as Miniature Circuit Breakers (MCBs) and Molded Case Circuit Breakers (MCCBs), to maintain system stability and prevent damage during fault conditions. Protective relays and devices have been developed over 100 years ago to provide "last line" of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions.
Protection schemes are an integral part of power systems as they ensure the safe and reliable operation of electrical networks. These schemes employ various relays, devices, and
